Title: Movement detection circuit
Inventor: NAKAYAMA HIROYUKI
IPC: H04N19/426
Filed: 1990-11-01
Abstract: PURPOSE:To reduce the capacity of a frame memory by applying nonlinear conversion to an inter-frame difference of a digital video signal so as to eliminate redundant information, delaying the signal by one frame so as to obtain inter-frame difference, applying nonlinear conversion to the difference and extracting the result as a moving quantity. CONSTITUTION:Let F2 be a current frame data, F1 be a data of one preceding frame and F0 be a data of two preceding frame, g(x) be a conversion characteristic of a nonlinear converter 8, then an output D of an adder 10 resulting from nonlinear-conversion of inter-frame difference and the sum of two resulting data is expressed in D=g(F1-F0)+g(F2-F1). Since a still picture component included in one-frame difference is F1-F0=-(F2-F1), it is required to have a relation of g(-x)=-g(x) to make the output D of the adder 10 zero. In the case of a moving picture, the relation of Dnot equal to 0 exists and an output of the adder 10 is an output equivalent to 2-frame difference. Thus, the capacity of a frame memory 9 is saved by selecting the conversion characteristic g(x) as above.
